Wikibrain 

the state in which you unconsciously jump from thought to thought due to extended exposure to Wikipedia's many random links.
An accompanying side effect could be the recitation of random and useless facts and stories. The person afflicted with Wikipedia Memory most likely does not understand what he or she is saying. See Wikipedia Scholar

Someone afflicted with Wikibrain should immediately see their local hospital for a castration, lest the stupid spread to any children.

"Hey man why didn't you do your homework?"
"I don't know, I was looking up how to do trigonometry when I ended up reading an article on Norton, the emperor of the United States. It seems he was insane."

"Man, you have some serious Wikibrain"

"Yeah... Btw did you know according to Cartesian Dualism there are dual commitments about the nature of existence as it relates to mind and matter? That means I exist in two places at once. Therefore, I can eat my burger twice!"
